Is removing and installing a blower motor and blower motor resistor challenging for home mechanics on Mazda 3?

This is not easy to undertake by home mechanics because of obscure fasteners, and difficult angles, and is best left to those of the more experienced do-it-yourselfers. When the blower motor is being removed, one should take a note of each part assembled in an orderly way, and this will make it easy to assemble the user again. Start by removing the battery cover and the negative battery terminal. The next step is to remove the steering column covers and instrument cluster, then remove the driver side scuff plate, kick panel, knee bolster, and the instrument cluster trim panel. Disconnect and pull out the steering shaft and the accelerator pedal pedal position sensor and then the brake pedal. Take out the resistor, disconnect the electrical connector with the resistor on the blower motor, remove the screws that hold it in place, and remove the resistor. On the blower motor removal, at least two persons are advisable so that no damage is caused to the fan. The ignition should be turned on, the A/C should be turned on to the FRESH air mode and the key should be switched off. Deassemble blower motor resistor, instrument panel trim strips, glove box assembly and Passenger Junction Box. Disassembly: Unscrew the radio and auto leveling control module and remove the floor air duct and remove the temporary steering stay when needed. Identify the blower case and air intake actuator and delete the blower case mounting screws as well as unplug the air intake actuator connector. Pinch the case of the blower a little forward, turn it around the firewall and take out the whole assembly. Take out the air guide of the evaporator housing and then insert a special tool on the blower motor. On the driver side, remove the electrical connector and the blower motor cooling tube, then pull the blower motor cover using the tab and turn it clockwise. Hold blower motor with an assistant to ensure that it does not fall into the evaporator case. Very carefully remove blower motor assembly. To install, insert the special service tool in the blower motor and insert the assembly in the housing, making sure that it is placed correctly. Install blower cover and press the locking tab and turn anticlockwise till it clips. Lastly, take off the special service tool and do the installation in that order.

Where is the blower motor resistor located and how do you replace it on Mazda MX-5 Miata?

On models with a mechanically controlled blower motor, the resistor of the blower motor is mounted on the blower motor housing before 2006. It is best to start with the ignition key being switched to OFF. Either take out the trim panel underneath the glove box and unplug the electrical connector of the blower motor resistor. Verify the continuity of the resistor side of the connector: In earlier models Continuity must be present between terminals 1A and 2A, 1A and 2B, 1A and 2C and 1A and 20. In models between the year 1997 and 2005, there should be continuity between terminals 1A-1B and 3A-3B, and also no continuity between the terminals 2A-2B, 2B-2C, and 2C-20. In case the continuity is not in these specifications, change the resistor. In order to replace it, it is necessary to take out the old resistor and fit a new one to the blower motor housing and re-connect the electrical connector. By this time, the engine will be started and the blower motor turned on and its proper operation checked at all speeds before replacing the lower trim panel below the glove box.

Mazda Blower Motor Resistor

In simple terms, the blower motor is responsible for driving air through your car's vents. You control the speed of the blower motor using switches, buttons, or knobs located on the dashboard. Inside a blower motor is another part called the Mazda blower motor resistor, which allows you to adjust the fan speed. Specifically, this component comes into play when one wants a reduction in fan speed; hence, it is used at lower settings (like 1, 2, and 3). The constant heating and cooling accompanied by dampness makes it easier for this particular resistor to corrode over time. Some common signs that signify a failing motor resistor include only high-speed fans working while slower ones fail, or none working at all. Such problems necessitate checking out the resistor and thinking about its replacement.

Whenever you need replacements, opt for genuine Mazda Blower Motor Resistors. Because they meet the manufacturer's criteria, it guarantees that replacements fit perfectly. Thus, these make better choices for people who care about driving. Why should you shop at MazdaPartsNow.com? We sell genuine Mazda Blower Motor Resistors.
